The function of Ensembl gene identifier ENSG00000165506 (DNAAF2, dynein axonemal assembly factor 2) is as follows. Required for cytoplasmic pre-assembly of axonemal dyneins, thereby playing a central role in motility in cilia and flagella. Involved in pre-assembly of dynein arm complexes in the cytoplasm before intraflagellar transport loads them for the ciliary compartment. .
